INTERNAL COMBUSTION ENGINE FiledMarch 17, 1937 2 Sheets-Sheet 2 Patented Sept 20,, 193$ srr INTERNAL coMBUs'rIoN ENGINE August A. Filicky, San mm sco, c. Application in 17, 1937, s s-m ne. 1.313% s (or; nae-5c) inder type wherein the cylinders are arranged in parallel pairs, each cylinder having its own piston and connecting rocltherein, and eoch of the connecting rods being rotatably mounted in onset relation to each other and in eccentric relation to a. crank shaft rotatably mounted in; the creole case of the engine.

A still further object of the invention is to provide on internal combustion engine hovingo crenlr shaft joumelecl therein, the said crank short having it poir ct reloteri throws thereon, each of which are separated radially relative to each other and eccentiicolly relative to the center of the crank shaft, whereby the connecting reels of o. oi perslleliy reciprocating pistons "will function to reciprocate sold pistons in the some pcth oi travel at ell times.

Uther objects of the invention are to provide it mnlttcyi torier internal combustion engine oi the four cycle type including pairs of cylinders arranged in porellel rows, wherein the piston in one cylinder on the downward stroke will snclr o cornhostilole mixture into the cylinder simultoneously with the firing oi the combustible mixture in the other cylinder, to etfect the downward movement of the piston in that cylinder, and. to provirle on internol combustion engine that will he superior in point of simplicity, inexpensiveness of construction, positiveness or operation, and

facility and convenience in use and general efi'q ciency; v

In this specification and the annexed drowings, the invention is illustrated in the form considered to "oethe best, but it is to be nnclerstood that the invention is not liniiteoi to such form, because it may be embodied in other forms? and it is also to be understood that in and by the cl following the description, it is desired to corclence. with my invention, a portion thereof being broken away to show the interior construction thereof.

In detail the construction illustrated in the drawings comprises the engine lolccl; l, crank case 2, cylinder hee'cl 3, crank shaft l, connecting rods 5, and pistons S. The engine loloclr throughout its length is provided with e. plurality of cylinders i, there being two rows of cylinders l, one on each side of the longitudinal center line of the engine block, thus providing; melti-psirs of cylinders l on both sides of the vertical center line of the engine block. Both the engine block l and cylinder head are water jacketed for cooling purposes, and the-engine block ported with the usual gas intake passages and eylienst ens posseges,-toeether with the valves 8, com shafts ii is rotateloly-monntecl on the throw it which entends between each of the pairs of plates it. The throws l2 ere moiintedradielly between the plates it with respect to the center sins of the crank shaft l and ere likewise located eccentricelly relative to sold ere-nix shei't axis. Each is the throws l2 between the pairs of plates ll, likewise have their centers ofiset or spaced escort, whereby the rotation of the creole shelf t will cause the pistons on the upper ends oi the connecting rods 5 to lie in substantially the some aligned plane during the reciprocetlve movement thereof. In other words each of the pistons 55 will reach the upmr'ancl lower limits of their reciprocetive movements at precisely the some time, and in oddition will be substantially seen with each other at intermediate positions of the reciprocetive oflset in two directions throughout their length end spark plugs it, all or" which conventional till . movement. Each of the connecting rods 5 are cylinder of each stroke of the pistons,

the compression stroke while the other would stroke, and vice versa. Similarly on the up one would be proceeding on and the wrist pins or be on the exhausting stroke and vice versa.

The firing arrangement of the engine would be such that it would pass alternately back and iorth across the longitudinalcenter line of the block. Likewise, with my construction it is only inder. In the conventional ing crank shaft throw necessary to have but a single gas intake to serve two cylinders in contradistinction to the conventional form of V-type engine wherein it is necessary to have a separate intake for each .cyl-

V-typc engine; the piston, connecting rod, and crank shaft arrangement is such that each piston operates in a differently timed relation to the piston directly opposite, whereas in my construction both pistons operate at the same time, and the power impulse directed against one piston is not retarded or minimized by the inertia of the pistondirectly opposite. In the ordinary V-type engine, a power impulse directed against one piston is to a certain extent reduced in efficiency by the lag of the piston directly opposite which, because of the timing and cycle of operation, is not in a position to commence its downward stroke with the piston to which the power impulse has been applied, and likewise, the same result is true on the up-stroke of the respective pistons.

With my invention, both pistons are timed to work together during all phases of operation and I have so timed the cycle of operation of the pistons that on the firing stroke of either piston, the other piston does not. tend to lag, and hence increases the operating efficiency of the engine.

Having thus described this invention, what I claim and desire to secure by Letters Patent is:

1. In an internal combustion engine, a cylinder block having plural pairs of parallel cylinders each of the cylinders of each pair lying opposite each other on a transverse plane at right angles to and,on each side of the center line of the engine crank shaft, pistonsslidably mounted in said cylinders; acrank shaft, a pair of ofiset throws on said crank shaft in substantial alignment with each pair of cylinders; and a connecting rod having a right angle and laterally oflset bend between each piston and matchwhereby the respective oil-center arrangement opposite each ,a pair of eccentric and offset throws approximately opposite each pair of cylinders; and a rod having a right angle and laterally oifset bend connecting each piston with one of the opposite throws whereby the respective pistons will move in substantially corresponding positions in the pair of cylinders during the reciprocatlve movements of said pistons.

3. The combination with an internal combus-,

tion engine having plural pairs of parallel cylinders each of the cylinders of each pair lying other on a transverse plane at right angles. to and on each side of the center line of the engine crank shaft; pistons slidably mounted in said cylinders; a crank shaft journaled lengthwise of andeccentrically between and beneath the pairs of parallel cylinders having a pair of eccentric and offset throws approximately opposite each pair of cylinders; and a rod having a right angle and laterally offset bend connecting each piston with one of the opposite throws whereby the respective pistons will move in approximately corresponding positions in the pair of cylinders during the reciprocative movements of said pistons.

4. The combination with an internal combustion engine having a pair of cylinders arranged with their central axes parallel, each of the cylinders of each pair lying opposite each other on a transverse plane at right angles to and on each side of the center line of the engine crank shaft; of a crank shaft arranged below and centrally between said cylinders; a pair of eccentric throws on said crank shaft, each being ofl'set relative to the other; pistons in said cylinders; and a rod having a right angle and laterally oiiset bend connecting-each of said pistons'to one of said crank throws whereby rotative movement of the crank shaft causes the respective pistons to lie in the same corresponding aligned position at the upper and lower limits of the reciprocative strokes, and permitting the firing and suction strokes and the compression and exhaust strokes of the pair of pistons to occur during exactly the same periods before the engine.
